Definitions
- the present invention pertains to a device for shifting an automatic transmission for motor vehicles, which has a selector lever, which makes possible an automatic upshifting and downing of the transmission in a first position as a function of the speed of the vehicle or the speed of rotation of the engine.
- Motor vehicles with an automatic transmission usually have a display field arranged in the dashboard for displaying the position of the selector lever arranged on the cardan tunnel.
- This has the advantage that the driver can ascertain the position of the selector lever by looking at the display and observe the traffic at the same time.
- What is still disadvantageous is that the driver looks at the selector lever block or the program selector during the operation of the selector lever or a program selector in order to shift over into the desired position of the selector lever or the program selector.
- a shifting device for an automatic transmission which has a selector lever guided in at least one shift gate, has been known from DE 40 05 588 A. Different gears can be preselected with this in both the automatic shift gate and a manual shift gate.
- the manual shifting in this shift gate has upshifting and downshifting positions which start from the middle position and can be shifted by a tipping movement.
- the automatic shifting is performed in the shift gate that has the gearshift positions such as the parking position, the reverse position and the forward position, which is performed by correspondingly displacing the selector lever in this shift gate.
- a steering column switch is used to shift the gears.
- a selector lever which is directly associated with the shift gates and can be actuated in the manner of a rocker type switch and which shifts the gears manually by moving into the upshift and downshift position, is provided in one exemplary embodiment.
- DE 43 24 788 C describes a motor vehicle with a power shift gear, which can be shifted automatically optionally by means of a selector lever associated with the shift gates or also manually, and the manual shifting can additionally also be performed by means of an actuating means arranged on the steering wheel instead of by means of the selector lever in the area of the shift gates when the selector lever is in the manual shift gate.
- This actuating means comprises a shifting rocker, which can be actuated with a finger and is embedded in at least one spoke of the steering wheel by means of a housing for manually upshifting and downshifting the transmission, wherein the shifting rocker with grip surfaces directed one after another in the longitudinal direction of the vehicle, with a pivot axis arranged at right angles to the steering wheel and with a shifting path in opposite directions between coaxially arranged push switches is pivotable and wherein the outer surface of the shifting rocker has a surface extending flush with the outer contour of the padding of the spoke.
- an actuating means for manually triggering the shifting operation of a motor vehicle transmission especially the stepped shifting operation of a continuously adjustable transmission
- This actuating means is arranged in the middle area of the steering wheel especially in the area of the baffle plate present there.
- the actuating means may have at least one button for triggering a gear shift or even two buttons, which are arranged directly next to one another or at spaced locations from one another, wherein one of the buttons is used for upshifting and the other button for downshifting.
- At least one finger usually the thumb, must be removed from the steering wheel rim to actuate one of the buttons in this case as well.
- the object of the present invention is to provide a device for shifting an automatic transmission, with which manual shifting of the transmission can be carried out from the steering wheel in an especially favorable manner m terms of grip and safety against operating error and which has a simple design and can be manufactured at low cost.
- a device for shifting an automatic transmission for motor vehicles is provided with a selector lever.
- the selector lever makes possible an automatic upshifting and downshifting of the transmission as a function of the speed of the vehicle and the speed of rotation of the engine in a first position and has an additional arrangement on the steering wheel, which makes possible a manual downshifting and upshifting.
- the additional arrangement is integrated within the steering wheel rim.
- the additional arrangement may be a segment of the steering wheel rim. This segment is mounted rotatably around the longitudinal axis of the rim and is designed as a button.
- the button may have two locked positions for the downshifting. The first locked position brings about a downshifting into the next lower gear and the second locked position brings about a downshifting into the lowest permissible gear at maximum speed.
- the additional arrangement may be a segment of the steering wheel rim which is elastically deformable around the longitudinal axis of the rim.
- a switch that can be actuated by a rotating force is associated with the segment.
- the switch may be a membrane switch.
- the switch may be a pressure sensor switch.
- the segment of the steering wheel rim which is mounted rotatably around its longitudinal axis or is elastically deformable, requires the application of only a weak force to make possible the manual downshifting or upshifting, and all fingers of the driver may remain on the steering wheel rim in the usual position.
- FIG. 1 is a top view of a steering wheel designed according to the present invention for the motor vehicle
- FIG. 2 a is a contact diagram for the button
- FIG. 2 b is a graphic representation of the force to be applied during the turning of the steering wheel segment
- FIG. 3 is a partial view of a steering wheel for a second exemplary embodiment
- FIG. 4 is a sectional view taken along line I—I in FIG. 3 .
- FIG. 1 shows a top view of a steering wheel, which comprises in the conventional manner a steering wheel rim 1 , which is connected via three spokes in this exemplary embodiment to a steering wheel hub, on which a collapsible pot is arranged, e.g., for accommodating an air bag.
- the steering wheel rim 1 has a segment 2 , which is integrated within the steering wheel rim 1 , i.e., has the same diameter, but is rotatable around the longitudinal axis. This rotatability is indicated by the bent double arrow in FIG. 1 .
- This segment 2 is advantageously designed as a button, so that shifting operations of the automatic transmission can be performed manually during the rotation of the segment 2 .
- the button of the steering wheel segment 2 has two locked positions for downshifting operations, where only simple downshifting into the next lower gear are carried out in the first locked position, while downshifting is performed into the lowest permissible gear in the second locked position at maximum speed.
- FIG. 2 a A corresponding contact diagram is shown in FIG. 2 a .
- the neutral position of the segment 2 is designated by 0, just as in FIG. 1.
- a slight turning of the segment 2 in FIG. 1 to the left ( ⁇ ) leads into the first locked position, i.e., to the contacting of a corresponding contact (shown top left in FIG. 2 a ); further turning leads to the contacting of a second contact (—) and thus to the second locked position, in which the downshifting is made possible at maximum speed into the lowest permissible gear.
- FIG. 2 b shows the force F necessary for these shifting operations, which is shown on the ordinate, while the turning angle of the segment 2 in degrees is shown on the abscissa.
- the manual shifting operation is activated by turning the segment 2 when either a switch is closed, e.g., the selector lever (not shown) is located on the shifting block of the cardan shaft in the manual shift gate or when the button contained in the segment 2 is actuated.
- the display in the dashboard is also switched with the actuation of the button and the requested shifting is performed.
- This manual shifting operation is abandoned when the manual switch is again set to automatic; if the manual shifting operation was requested in the automatic mode, the manual operation can take place by actuating the segment 2 in the opposite direction (+in FIG. 2) beyond a certain time, e.g., 1 sec, and the contacting indicated in the top right part of FIG. 2 a with a plus sign now takes place.
- a certain time e.g. 1 sec
- the segment 2 is no longer integrated here rotatably around its longitudinal axis in the steering wheel rim 1 , but is designed as an elastically deformable segment.
- a corresponding switch e.g., a membrane switch or a pressure sensor switch, with which the desired manual shifting is initiated, is integrated in the segment 2 of the steering wheel rim 1 .
- the steering wheel comprises in the usual manner a steering wheel core 3 made, e.g., of metal, which is surrounded by a foam 4 , which is covered by a cover, e.g., a leather cover 5 .
- a membrane switch designated by 7 or a pressure sensor switch is rigidly connected to the steering wheel core 3 , and plates 6 , made, e.g., of plastic, are arranged on both sides.
- Prior-art membrane switches have an electric internal resistance proportional to the actuating force, e.g., a resistance range from 2 M ⁇ at a pressing force of 0.1 N to 1 K ⁇ at 100 N.
- the desired point at which the corresponding downshifting shall be triggered by contacting the membrane switch or the pressure sensor switch could thus be coordinated accurately in the corresponding electronic unit for the automatic transmission. Only one pressure sensor switch is needed in this exemplary embodiment for the simple downshifting into the next lower gear and for the downshifting at maximum speed into the lowest permissible gear.
